Wow!
I just ordered the N62 timing tools and the overhead valve spring compressor to replace my valve seals on my 6er. I should have seen this first.
I wonder if I call up AGA if they would be able to have a version of the tool they can sell me.
I want to replace my valve seals but shudder at the idea of removing the camshafts and adjusting the timing.

Are you going to wait for AGAs tool or pull your cams? You can pay your registration and smog it later.
